Science and uses
Composition
The most important mineral component of lapis lazuli is
lazurite (25% to 40%), a blue
feldspathoid silicate mineral with the formula . Most lapis lazuli also contains
calcite (white),
sodalite (blue), and
pyrite

as a result of
contact metamorphism.
Color

The intense blue color is due to the presence of the
trisulfur radical anion () in the crystal. The presence of disulfur () and tetrasulfur () radicals can shift the color towards yellow or red, respectively. These radical anions substitute for the chloride anions within the
sodalite structure. The radical anion exhibits a visible absorption band in the range 595–620 nm with high molar absorptivity, leading to its bright blue color.

, but most scholars agree that, since sapphire was not known before the Roman Empire, they most likely are references to lapis lazuli. For instance, Exodus 24:10: "And they saw the God of Israel, and there was under his feet as it were a paved work of a sapphire stone..." (KJV). The words used in the Latin Vulgate Bible in this citation are "quasi opus lapidis sapphirini", the terms for lapis lazuli. Modern translations of the Bible, such as the New Living Translation Second Edition, refer to lapis lazuli in most instances instead of sapphire.
